# Firewall settings It's important to give the CCS Web Server permission to communicate through the firewall on your PC. If not the CCS browser Apps will not work on any PC other than the server PC because the server will not be able to respond to any requests from remote PCs. This persmission can be set via the control panel. Select 'System Security / Windows Firewall / Allow a program through Windows Firewall' . You may have to click a further option depending on which version of Windows you are running. Eventually you will see alist of programs/apps that need permission to communicate throug the firewall. In the list locate 'ccswenserver.exe'. You must check both the public and private checkboxes for this program. You may need to click 'Change settings' before being allowed to modify the settings. Make sure both options are checked for 'ccswebserver.exe' and apply the changes by clicking 'OK' at the bottom of the window.
